Bright spot on the bowel or echogenecity is a normal finding in many cases. Reduced bowel movement in the fetus, low maternal belly fat and blood in the amniotic fluid
are some of the causes for such an observation. Sometimes, it is seen associated with poor fetal growth, cystic fibrosis
, intestinal blockage, chromosomal anomalies and fetal infection
. Blood tests, amniocentesis
(if absolutely necessary) and high resolution ultrasound are to be done. Hope this helps.
